Question

if the volume of a sphere is numerically equal to its surface area,then find the dimameter of the sphere​

Answer 1

Step-by-step explanation:

volume of sphere= 4/3πr³

surface area of sphere=4πr²

given that-volume of sphere=surface area of sphere.

4/3πr³=4πr²

r/3=1

r=3

if radius=3 then diameter will become double i.e.2×3=6
